java代碼:

//清空數據
	private void ShowPopup() {
		LayoutInflater mLayoutInflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
		ViewGroup mView = (ViewGroup) mLayoutInflater.inflate(
				R.layout.soft_calendar_popup, null, true);
		final PopupWindow popupWindow = new PopupWindow(mView,
				LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, true);
		final RadioButton radio1 = (RadioButton) mView
				.findViewById(R.id.radio0);
		final RadioButton radio2 = (RadioButton) mView
				.findViewById(R.id.radio1);
		final RadioButton radio3 = (RadioButton) mView
				.findViewById(R.id.radio2);

		Button btn1 = (Button) mView.findViewById(R.id.button1);
		btn1.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				//確定按鈕實現的操作 
				popupWindow.dismiss();
			}
		});
		Button btn2 = (Button) mView.findViewById(R.id.button2);
		btn2.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				// 取消按鈕實現的操作
				popupWindow.dismiss();
			}
		});

		popupWindow.setBackgroundDrawable(new BitmapDrawable());
		popupWindow.showAtLocation(findViewById(R.id.RelativeLayout1),
				Gravity.CENTER | Gravity.CENTER, 0, 0);//在屏幕的中間位置顯示
		popupWindow.update();

}
